Application fried May 23, 1922. Aserial No. 563,024.

T all whom t may concern.' l Y Be it known that I, .losnrn A. VILKIN, acitizen of the United States, and resident of the town of Matamoras,county of Pike, State of Pennsylvania, have invented cer tain new anduseful Improvements in Turn stiles, of which the following is thespecilication.

The device, the subject of this invention is a turn stile, particularlyadapted for use at amusement parks, railway 1stations or else wherewhere passenger or passage trailic is to be collected and has for itsparticular objects the construction of a turn stile that will bepositive in its operation and yet particularly silent as the continuoususe of a noisy turn stile is exceedingly irritating.

Another object of the invention is to produce a turn stile soconstructed that continuous operation is practically assured, the partsbeing so formed as to withstand continued and excessive wear. I have,however, so constructed my turn stile that if wear does occur, the wornparts or the parts subject to wear may be readily removed and replacedand while my turn stile may op crate with a coin controlled electricalreleasing means, I will show and describe such means only briefly asthey are not intended to form an important part of this invention.

In the specification which follows, the details of construction andother objects will be fully set forth and the accompanying drawingsshould be referred to for a complete understanding of the lspeciiicationwhich follows In the drawings Fig. l, is a plan view, the casing beingfractured to show the enclosed mechanism.

Fig. 2, is a sectional view through the casing and track, the othermechanisms being shown in elevation.

Fig. 3, is a perspective View of the turn stile element.

Fig. 4, an enlarged sectional View, at about mid-center the controllingmechanism.

Fig. 5, is an enlarged sectional view through the controlling roller andits support.

Similar reference numerals indicate like parts in all the figures wherethey appear.

The turn stile consists of a cross shaped member having arms 6, 7, 8,and 9 and between which the passenger or operator will step to operatethe turn stile.

The arms 6 to 9 inclusive are supported upon a standard or column lO andas the arms should be formed of wood, I will pro vide supporting plates11 and 12 upon the standard 10, one at each side of the arms and betweeneach the arms are receiver and secured by bolts or rivets 13.l

The standard may be continuous throughout its entire length, the lowerend should, however, be reduced as shown at 14 to be received into thebearing block 15 an'dto overcome undue friction, the lower end of thestandard 10 may be tapered to produce a cone bearing 16.

The controlling mechanism for the turn stile is received in the casing,preferably formed in two parts 17 and 13, secured together by. bolts 19and= in securing these parts together, Iv include and retain by the mbolts 19, a track guide member 20.

Upon the standard 10 and within the casing, I arrange a collar 21,securing thereto a pair of guide rails as shown at 22 and 23 and spacedtherefrom, I 4arrange another pair of guide rails 24 and 25. In eachpair of guide rails, I arrange T-shaped guides 26 1 and 27 securedtogether by a bolt 28 and upon this bolt and between the guides 26 and27 is a grooved pulley 29. It will be noted that at the opposite side ofthe standard 10, another pair of guides 30 and a grooved pulley 31 arearranged and that these guides and their supported pulleys are urged outward by springs 32 and 33. i

The springs 32 and 33 arranged parallel, are received in cup members 34.35, 36, and 37, which cup members are secured to bars 38 and 39, thebarsyhaving projections 40 and 4l, which bear against the innermostedges of the guide members 26, 27, and respectively.

The lower guide rails 24 and 25 may be secured to a collar 42 andadjacent this collar, I arrange a plate 43 having a plurality of indents44, into which the core 45 of a solenoid 46 may be inserted. This coremember 45 has a spring pressed latch and may be cut at an angle in onedirection, so that operating with the angular indents 44 in the plate43, the turn stile may operate freely in one direction, but may operatein the other direction only when the core member 45 is electricallywithdrawn.

One of the most important parts of my device is the track member 20 uponwhich the rollers 29 and 31 operate. This member is shown in plan inFig. l and its operation will be understood. The rollers as shown inFig. l are in the stop position.

lVhen the turn stile is advanced until the roller 3l reaches the point47 and the opposite roller reaches the point 48 and passes just beyondthat point, the operation of the springs 32 and 33 will cause the turnstile to continue in movement until the rollers meet the depressions 49and 5t), at which time the motion of the turn stile will be arresteduntil the next application of pressure causes the rollers to advancebeyond the projection 51 and the projection directly opposite, whereuponthe rollers will move into the position shown.

liilhile modifications may be made within the scope of the appendedclaims, I prefer the whole as shown and described; it will, however, beunderstood that the rollers 29 and 3l, the guide bars 22 to 25 inclusiveand the track member 2() may be 'formed ot' wood if preferred, the otherparts, with the exception of the arms lo 9 should be oli metal.

Having carefully and lully described my invention what l. claim anddesire to obtain is as 'ollows:

1. A turn stile having; a casing, an irregu- Lacasse lar track securedto said casing, a standard ope able through said casing, rollerssupported by and movable with said standard and in engagement with saidtrack and means il'or urging` said rollers toward said track, said meanscomprisingsprings, one arranged at each side of said standard.

2. A turn stile comprising` a standard and an irregular track in fixedrelation, guide bars secured to said standard and eXtendine,` at eachside thereof, carriages operable in said guide bars, one said carriagebeing arranged at each side @t said standard, a roller in each saidcarriage and operable upon said track and a plurality of springs betweensaid carriages for urging` said rollers toward said track.

3. In a turn stile, a means for controlling the operation thereof, saidmeans comprise ing two sets of parallel guide bars, carriages betweenpairs of bars, rollers upon said guides and means for urging` saidrollers and guides outward and a track having a plurality of depressionsof liil'erent depths, into which said rollers are 'free to pass tocontrol the movement of said turn stile.
